Expert reviews of UK online casino sites

Online.Casino separates the good from the bad so that you don’t have to.
This might not sound like much, but we’ll tell you why it matters.

With so many different websites out there, it is almost impossible for an individual to research them all.

Let alone find the best, most reliable and secure online casinos.

Even if one person could do it, it would leave them with little to no time to enjoy gambling at any of these sites.

At Online.Casino, our team of unbiased experts has done all the hard work for you. We have provided you with a comprehensive guide to the safest, most reliable and best online casinos in the UK.

We rate, review and rank every online casino that we believe is worth visiting and we use strict parameters to decide which are the best.

And to be frank; we do not list websites that do not measure up to our exacting standards.

In other words, far from all the iGaming websites that we visit are featured on our site.

First and foremost, we ensure that every online casino reviewed and listed on our site has a valid license from the UK Gambling Commission.
This means they have legal rights to operate in the UK.

Once we have established the casino licence and credentials of a site, we look at how user-friendly the site is and how accessible it is from both your desktop or mobile device.

Features that we consider when reviewing UK online casino sites are:

  • Promotions and campaigns
  • Website theme and design
  • Safety and security
  • Licenses
  • Game selection
  • Customer service
  • Mobile play options
  • Payment methods

All our reviews are carried out by unbiased experts and we do our best to ensure that only safe and reliable operators are listed on Online.Casino.

We also realise that different sites appeal to different people. This is why we recommend you to visit numerous online casino websites, to find the one that suits you best.

Before you join a UK online casino or commit to playing with real money, use our reviews to ensure that the site is safe and reliable.

What do the top-rated UK casino sites have in common?

With so many online casinos out there, we need to have guidelines and criteria that help us in the review process.

These guidelines help us decide which are the best online casinos in the UK and what they have in common. The top UK casinos offer:

  • A wide variety of games. These are the main drawcard for any top casino
  • A good mobile experience. With online gambling becoming increasingly popular, more people than ever before want to play on the go and this makes a great mobile experience essential
  • High levels of security. Like all online activity, safety and security is paramount for casino websites
  • Large bonuses with fair terms. Everybody wants the opportunity to win big
  • Multiple convenient payment methods, secure deposits, and fast payouts. The easier and more convenient it is to deposit money and receive payouts, the more players will enjoy their online gambling
  • Tax-free winnings. Everybody wants to be able to keep 100% of their winnings and not share the money with the taxman
  • Reliable, English speaking support. All the best UK online casinos have English speaking customer support that is available 24/7 via live chat or email

At Online.Casino we look for the best online casinos that offer players a great gambling experience and the opportunity to win big. Without any hassle.

Big game selection from the best game providers

In order to compete in the highly competitive market of online gambling, casinos do their utmost to attract players.

This means that the best casino sites in the UK, both established and new, need to offer a wide selection of entertaining games.

And they need to be from the top game providers.

We know for a fact that players would not enjoy a casino as much if games from Microgaming or Play N’ GO was missing.

It is important to remember that online casinos never create the casino games themselves.

Instead, they work closely with software providers.

For example, the casino games on Williamhill.com comes from NetEnt, Microgaming and Evolution Gaming among others.

Just like there are niched casinos, different software providers specialise in different types of games.

That is why the top casino sites in the UK will feature games from various software providers. This brings variety and depth to the game selection.

These will include slot games, table games, live casino games, and progressive jackpots.

Evolution Gaming is currently the premier provider of live casino games, while the best slot games are developed by NetEnt and Microgaming.

Identifying the best UK casino sites

If you want to identify the best new UK online casinos, you need to take a close look at which game providers they use before you sign up and start playing.

Many players consider the number of games one of the most important aspects when choosing a new place to play.

This makes having a wide selection of games from the premier game providers even more important for operators.

This ensures steady growth of new slot games, so the customers never get bored.

For example, some of the best casino games launched in 2019 are Jumanji, Witchcraft Academy, Berryburst and Playboy Gold.

All very popular with UK players.

Great mobile experience

Mobile phones are the most popular gaming devices among online gamblers. And today, all UK casinos offer mobile gaming.

The gambling experience is equal to that of playing at your desktop or laptop, if not better.

Mobile casino sites in the UK used to be very basic and needed to be downloaded to your tablet or smartphone before you could start playing.

But luckily the mobile gambling industry has evolved rapidly over the last few years.

Now most UK casino sites can be accessed without downloading any files to your mobile device.

It doesn’t matter if you have an Android phone, iPhone, iPad or tablet. You can now play all your favourite games and slot machines directly from your browser.

With the growth of the mobile games market, all the top software providers are now developing new slot machine games and table games.

As well as being fun and rewarding, they work on any mobile device. This is due to games being build with HTML5 technology, with responsiveness in mind.

How to casinos and game providers work together?

So how does the co-operation between casinos and game providers work?

In a nutshell, casinos are mere a portal or a library of games. A bit like Netflix or Spotify.

The game providers in this scenario are the creators of the content presented in the casino lobby.

The game providers strike a deal with the operators to showcase their games in their lobby, and in return, they get a percentage from the profits.

This means that the game providers can showcase their games on hundreds of gambling sites at once, and get a cut from all the revenue.

This makes game providers the big winners, and the stock value proves it. IGT, one of the biggest providers of casino games in the world have at this time a stock value of 2.74 billion dollars.

Safe and secure online gambling

Safety and security are paramount on the internet. This means that any online casino site that wants to be rated as one of the best in the UK needs to pay particular attention to their security.

Also, the UK Gambling Commission is very concerned for the social responsibility and the approach casinos have towards anti-money laundering, which they stated in a letter to all online casino operators.

Offering a safe environment for all their players goes hand in hand with being a successful operator.

Safety features that we, at Online.Casino consider when rating an online gambling site include;

  • Casino licence issued by the UK Gambling Commission
  • SSL protocol and data encryption
  • Accreditation by eCorga and other testing agencies
  • Good online reputation
  • Responsible gaming measures
  • Safe and secure banking methods for both deposits and pay-outs
  • Fair games with RNGs (random number generators) that offer the opportunity to win big
  • Reliable, English speaking customer support

The UK gambling industry is totally legal and highly regulated. This means you can play safe and legal at all the best UK casino sites.

Good gambling sites offer safe, secure deposit and pay-out options and are always fully encrypted and verified.

This is to ensure that your personal details and financial information remains secure at all times.

So how do you go about finding safe options?

It’s easy.

At Online.Casino, we only present the best secure online UK casinos where you can safely enjoy your online gambling experience.

Choose any of the options we present, and you should be good to go.

Large bonuses, with fair terms

Everyone gambles to win big, that’s the whole point.

And, of course, you want to have fun while you do it.

At Online.Casino we spend hours testing UK casinos, and when we rate and review sites, we look closely at all their offers and promotions.

This includes welcome bonuses, free spins, loyalty rewards and VIP programs.

We also look closely at the terms, conditions and wagering requirements of every site that we review.

This is to make sure that the sites we feature on Online.Casino has fair terms with clear explanations.

In our opinion, the best casino sites offer large bonuses with no wagering requirements, but there are not that many of these.

As we want all our clients to know exactly what they are getting when they choose to join an online casino in the UK, we present more data than any other site.

That’s why we believe you will love using Online.Casino.

You do not need to take our word for it.

Instead, let the data talk for itself.

This way you can compare bonuses and other offers, and be sure you’ve made the right choice.

Multiple payment methods without fees

If you are a regular online casino player, it is important to know about the various deposit and withdrawal methods.

It’s also good to know the rules and potential fees that might apply.

Just as gambling on the internet has grown phenomenally over the last few years, so have the payment methods available on all top casino sites.

Online casinos understand that you want your payments to be seamless and you don’t want to struggle with complicated or time-consuming payment methods.

The two most common payment methods accepted by almost all casinos are E-Wallets or with debit/credit cards. This means both deposits and withdrawals.

E-wallets are currently the most popular payment method at online casinos and are usually the best option for players.

Their main advantage is security.

When you have an e-wallet you can protect your personal and financial information from third parties and have multiple sources of money linked to just one anonymous account.

Sending money to online casinos via credit or debit card is also very easy.

This was by far the most common and trusted payment method at top casinos until a couple of years ago.

The fee for credit card transactions varies a lot, but within the EU there are usually no fees.

With both e-wallets and debit/credit cards, the deposited money will appear in your account immediately.

Secure deposits and fast pay-outs

With all the potential security breaches out there, online security has never been more important.

And especially when dealing with deposits and pay-outs.

When choosing a UK casino site, it is essential to ensure that they have top-notch security and that all deposits, withdrawals, and pay-outs are encrypted.

Every casino site in the UK has a payment setting page. Here you can see all the available payment methods and pay out times.

E-wallets are generally the fastest and most secure payment method at UK gambling sites.

They are designed for instant use and they are fully optimised for speedy deposits and withdrawals.

However, all casinos work differently, and deposit and withdrawal times vary greatly at UK casino sites.

To be sure, you need to read the terms and conditions of each site (or read our reviews where we state this clearly).

One very important factor to consider when choosing a payment method is the level of security.

E-wallets are currently the safest payment option because you don’t have to hand out any personal or financial information to a third party.

Also you require a personal password to access your e-wallet.

PayPal is accepted by most casinos and is an increasingly popular payment option we can recommend.

Tax-free winnings

Nobody likes paying taxes and tax-free winnings are one of the great advantages of gambling at UK casino websites.

In many countries, the money you win gambling is part of your taxable income but fortunately, this is not the case in the UK.

Prior to 2001, there was a betting duty of 6.75% on all gambling winnings in the UK.

However, as part of Gordon Brown’s budget reform, all player’s proceeds from gambling became tax-free as of 2001.

This means that whether you play at a traditional brick-and-mortar casino or a casino website, you can keep all the money you win.

Also, you are under no obligation to report it to the government as it is not part of your taxable income.

The UK government does not differentiate between occasional and professional gamblers, so even if gambling is your main source of income, you will not be taxed on your winnings.

Many people speculate that the government removed the tax on gambling winnings in an attempt to keep online and traditional casino operators in the country and retain the jobs and revenue generated by the industry.

Casinos are charged a point of consumption tax of 15% but this does not affect players. This tax will be raised to 21% by the 1st of October 2019.

Reliable English-speaking support

Reliable customer support is vital for any casino site in the UK.

Players often have questions and queries that need to be answered, and they do not want to wait for business hours.

These can range from practical questions regarding payment options, registration details and deposit methods to more serious concerns like self-exclusion and online security.

Most casino sites have an FAQ section on their website but they also offer 24/7 online support via live chat, telephone or email.

At Online.Casino, we ensure that all the sites we rate, review and feature on our site have reliable English-speaking support that is available day and night.

The details of Gamblers Anonymous and GamCare should also be available on all sites. This is important so players know where to turn if they want to stop gambling.

Online customer support should be available 24/7 to help you self-exclude, set deposit limits or edit parental control options as well as answering any questions you may have.

Our recommended online casinos don’t just offer their players the most exciting games, they also have a reliable support centre.

Always first with new casino sites in the UK

New casinos are being launched regularly and at Online.Casino we do our best to keep you up-to-date with all releases.

Why would anyone want to play at new casino sites, you might ask?
Well firstly, a big factor is the big welcome bonuses handed out on the first deposit.

And secondly, many new casino sites are more modern and bring the evolution of gaming sites forward.

Without new casinos we would never have seen products like Casumo, Dunder or CasinoHeroes.

All three UK favourites loved by thousands of players.

When we rate all new casino sites in the UK, we do it according to the following criteria:

  • Bonus offers
  • Customer Support
  • Wagering requirements
  • banking Methods
  • Mobile-friendliness
  • Game Selection
  • Design and feel
  • Licensing
  • Security
  • Customer support

When presenting casinos we go into detail. This way it’s easy for you to see if a casino has a UK Gambling Commission, and if they have fees on deposits.

We bring you the data. You make the decisions.

New casino sites are one of the best places to gamble and we’ll tell you why.
They are trying so hard to attract new players and therefore, they offer the best deals and more games.

These sites want as many players as possible to try out their games and recommend their site to other players.

For this reason, they have awesome free spin no deposit bonuses and welcome offers for new customers.

Another attractive feature is that some new casino sites have no wagering requirements on their promotions.

If you sign up to play at a new casino you will most likely get a welcome bonus. And compared to the bonuses you would get from an established operator, you would be better of playing on a new site.

Hower, bonuses are not all that matter.

At Online.Casino we know that our visitors are searching for new UK casino websites, with high security and safety for players.

This is why we only feature the best new online casinos and give each one an independent review and rating.

Also, we offer exclusive deals at many of the featured sites to help you find the option that suits your needs.

Huge database of UK mobile casino sites

With so many operators competing to get your attention, it is hardly surprising that many have chosen to focus on the mobile segment.

This way, making it possible for you to use your smartphone or mobile device to play casino games on the go and win real money.

Many software providers now design unique mobile slots and table games specifically for this reason.

The best thing is that you can access these sites directly from your smartphone without downloading any files.

No apps needed, if you don’t prefer it.

But before you chose a mobile casino, you need to review the technical specifications of the site. This is to ensure that your smartphone is compatible with the site software.

The easy way to do this is to have a quick browse on our reviews, as we have this info listed under the details of a casino.

This might sound tricky, but the truth is you can play most slots and casino games on android devices, iPhones or iPads.

But with so many great mobile casinos available, it can be hard to find the best sites, promotions, and games.

That is where we can help you.

At Online.Casino we do all the research and hard work to find the best casino sites and add them to our massive database.

We make sure that we review and rate as many mobile casinos as possible and add them to our comprehensive list.

We do this because we realise that when you’re in a hurry, you don’t want to spend ages trying to find a mobile casino site that you enjoy.

Use custom filters to find your best match

At Online.Casino you can use our impressive filter to find all the UK operators available and then narrow them down to the ones that offer what you are looking for.

Using our database and filter you can compare features like games, special offers, promotions, and app functionality.

This makes it quick and easy to find a mobile casino that you like.

Slots and online casino games in abundance

There are many different types of casino games. This includes classic table games, like roulette and blackjack, live casino games, lotteries, bingo, and progressive jackpots.

But of all the online casino games, the most popular are the slot machines.

Here at Online.Casino, we have reviewed thousands of video and classic slots so that we can help you find the ones that you enjoy the most.

Even better, you can first play many of these slots for free on our site in DEMO mode before you decide which ones you like best.

Slots or one-armed bandits, as they are often referred to, have been around for years.

They have always been popular in traditional brick-and-mortar casinos because they are fun and easy to play. Also, they give you the opportunity to win real money (and to win really big).

The appeal of slots has adapted well to the online platform and they are now just as popular online as they ever were at brick-and-mortar casinos.

Slot machines are so popular because they are quick to master and easy to play but they also provide an opportunity to win large amounts of money.

Many slot sites offer free spins, no deposit bonuses and other great promotional offers that give you many hours of entertainment.

Choose a casino with games you like

Depending on which online casino site you choose to play at, the variety of slot machines to choose from can be huge.

Some of the smaller operators, for example, don’t offer progressive jackpots where you can win millions on a single spin.

Those games are exclusively for bigger sites, with more players adding to the jackpot.

However, most online casinos have a wide selection of slots from various software providers. It is also common to find slot machines with specific themes.

These are often based on famous movies.

For example, Jumanji, The Beverly Hillbillies, The Godfather, and Ghostbusters.

There are also 3-D slots, TV-themed slots and Game Show slots.

NetEnt is currently the premier developer of online slots, and their games can be found on all the best online gambling sites.

The biggest jackpot slots in the UK

Progressive slots are the only online casino games that offer players the opportunity to win life-changing jackpot prizes.

Most slot machines have a fixed limit, but a progressive jackpot increases every time the game is played until it is won.

This means there is no limit to the amount that can be won on a single spin.

There are three different types of progressive jackpot slots; standalone progressive jackpots, local progressive jackpots and wide area network progressive jackpots.

With a standalone progressive jackpot, only the bets placed on that particular game add to the value of the jackpot.

Local progressive jackpots link slots on a specific online casino site.

Wide area network progressive jackpots are one of the most popular casino games. They link jackpots on multiple casinos together, making the prizes much bigger.

To make the progressive jackpot grow faster, multiple slot machine games are linked together.

This way, many people are constantly contributing towards the jackpot.

Microgaming hosts a jackpot system where multiple games contribute to the pool and it has paid out a record amount of €18 915 872.

Not to bad for a single spin.

Are there any stategies to win a progressive jackpot?

Unfortunately, there is no strategy or system that can increase your chances of winning a progressive jackpot.

And with odds similar to winning the lottery, it’s not likely you’ll ever hit the big win.

Because there is no limit on the size of the jackpot, these machines never come ‘due’ and they do not have to pay out and this makes the chances of winning astronomically small.

However, sometimes they do hit, and one lucky player takes home a life-changing amount of money.

The most popular progressive slots are Mega Fortune, Megabucks, Elvis, Mega Moolah and Wheel of Fortune.

Progressive jackpots may have the biggest pay-outs of all the jackpots, but if you get really lucky and win the big prize, some progressive jackpots will not pay out the full amount in one payment.

Instead, it is usually paid as an annuity over 25 years.

Advantages of joining multiple casino sites

There are an unbelievable number of casino sites out there and they are all competing for your attention.

Every online casino wants you to try their products and recommend it to friends.

That is how they grow their business.

In order to attract as many players as possible, online casinos have deposit offers and various other promotions such as loyalty programs.

Fortunately for online gamblers, you don’t have to restrict yourself to only playing at one gambling site.

You can be a member of multiple sites and enjoy all their casino promotions and special offers.

Joining multiple casino sites is a no brainer as it means you can get more bonus offers and promotions. This increases your odds of getting the edge over the casino and the chances of winning more money.

Online casinos all offer different promotions. Some will give you no deposit free spins and no deposit bonuses, while others will have better VIP and loyalty programs.

Each offer also has its own wagering requirements and all these factors can influence where you feel like playing at any given time.

A way to try more games

Of course, not every online casino can offer every game available.

So by joining various online gambling sites you can enjoy a wider variety of games and find new and exciting games on every site that you become a member.

UK casino sites all have different designs and graphics, and therefore each one has its own unique feel.

And just like you don’t want to eat at the same restaurant every time you go out, you don’t want to visit the same casino website every time you play.

Sometimes you want to mix it up a bit and experience a different vibe.

Make sure to play at UK casino sites

With so many casino sites on the internet, it is important that you know where a site is based and licensed before you become a member.

If you live in Britain it is best to only join UK based online casinos because they are all licensed and controlled by the UK Gambling Commission.

The gambling industry in the UK is well controlled and this means that all casino sites are entirely legal, regulated and meet certain standards.

This makes these sites safe and secure places for you to enjoy gambling.

It really is not worth taking a chance and risking all your money at some dodgy fly-by-night casino that may not pay-out your winnings.

Don’t risk it at non-UK casino sites

Many legitimate casino sites that are not licenced in the UK will use great promotions and bonus offers to try and persuade you to join their sites. This is not advisable.

Not only do you not know if these online gambling sites are properly regulated and controlled, depending on where they are based, but your winnings also may not be tax-free and once you have paid tax on your winnings, it could cost you more than you have won.

With so many well-established casinos in the UK and so many new sites being launched, and all offering awesome promotions and deals, there really is no reason to join a gambling website that is not based in the United Kingdom.

At Online.Casino we have put together a comprehensive list of all the top casino operators in the United Kingdom.

We ensure that all the sites we feature are licensed by the UK Gambling Commission, and support fair gaming.

Use our site to find safe, trustworthy options where you can gamble with peace of mind.
